Vehicle energy management system

A system comprising:

• one or more processors configured to:
• determine multiple fuel components that represent fuel consumption by a vehicle system completing a trip over one or more routes;
• generate or modify a trip plan that designates operational settings of the vehicle system at one or more of different locations, different distances along the one or more routes, or different times;
• generate or modify the trip plan based on the multiple fuel components;
• determine total energy requirements during a trip;
• determine speed requirements during plural sections of the trip of a vehicle system based on the total energy requirements;
• determine at least one speed restriction section of the plural sections of the trip based on the speed requirements that are determined;
• and
• modify the trip plan based on the total energy requirement determined, the trip plan designating the operational settings within at least the at least one speed restriction section;
• and
• control an operation of a propulsion system or a braking system of the vehicle system based on the generated or modified trip plan,
• wherein the multiple fuel components that are determined by the one or more processors comprise a drag variation of the vehicle system at a mean speed of the vehicle system, wherein the drag variation is a function of a first, a second, and a third statistical moment of the mean speed of the vehicle system and two or more of:
• a delta elevation component of the one or more routes,
• a delta speed component of the trip,
• a mean drag component of the vehicle system,
• a curvature component of the one or more routes,
• a base fuel component of the vehicle system,
• a minimum braking component of the vehicle system,
• a braking auxiliaries component of the vehicle system, or
• a drag variation of the vehicle system.
